Abstract:An alloy with the composition of 49.6Ni-35.4Ti-9Hf-6Ta (at%) was processed by high-pressure torsion (HPT) and post-HPT annealing treatment. The microhardness of HPT-processed samples increased obviously, and amorphous feature appeared in 2 turns sample. The microhardness further increased and amorhozation was enhanced in 16 turns sample. After annealing at 750 ℃ for 3h, almost full crystallization occurs in 16 turns sample. In-situ high temperature X-ray diffraction experiment reveals that martensite to austenite transformation took place, indicating the alloy would exhibit SMA effect.
